Claims. (Cl. 242-39) This invention relates to machines for winding material such as thread, cord, filaments,- wire and the like, hereinafter referred to as thread, into package form. The invention provides a new apparatus which stops the operation of the winding machine when the package has reached a predetermined size.

An important advantage of the new thread package sizing device is that it makes possible the production of thread packages of uniform size without any objectionable pressure being exerted against the package in the course of its production. Such pressures frequently cause unevenness in the package being wound and may in some cases damage the thread. The device of this invention is particularly well adapted to be used on the conventional type of package winding machine and may be installed on such machines in a relatively simple manner.

The conventional winding or coming machine is provided with a rotating thread collecting spindle and a frame member which is so constructed and arranged as to recede from the spindle in correspondence with the growth of the thread package being wound thereon. Such machines are also provided with a mechanism for stopping the spindle if the thread being wound thereon should break. This mechanism is usually actuated by a lever which is connected,

to a member adapted to engage a rotating notched wheel sometimes referred to as a knockoff wheel.

The package sizing device of the invention is advantageously pivoted on this lever of the coning or windin machine and is also connected to the frame member of the machine. The device is so constructed that when the frame member has receded from the spindle a predetermined distance, the device will engage the knockoff wheel and actuate the lever which in turn will cause the spindle-stopping mechanism to function.

The invention will be further illustrated by reference to the accompanying drawings in which Figure 1 represents a front elevation of the device of the invention mounted on a conventional thread-winding'machine with parts of this machine being broken away in the interest of clarity; Figure 2 is a side elevation of the device with certain parts broken away; and Figure 3 represents a, preferred embodiment of the shaft l0 upon which is mounted a cam (not shown) which operates to reciprocate rod II to which is secured thread guide l2. Both the thread guide and the reciprocating rod are supported by a frame member l5 which is pivotally mounted on cam shaft ,lli by means of support Hi. If desired, the thread guide I2 may be in contact with the thread package l8 which is mounted on the spindle I9 so that the guide and its supportin frame member 15 recede from the spindle I!) as the package grows in size.

The conventional coning machine is also provided with a device whichstops the rotation of the spindle when the thread being supplied to the spindle breaks. The thread break stopping device (not shown) may be of the type illustrated The de- I in U. S. Patent 801,941 to Wardwell. vice is actuated by raising lever sector 20 which is pivotally mounted on pin 2| and which is provided with detent mean 23 which, upon being released, causes the stopping mechanism to operate. Pivotally mounted on pin 25 of lever 20 is anL-shaped member 26 having arms 21 and invention wherein the threaded arm has been given a quarter of a turn to illustrate its structure.

The conventional coning machine sho'wn has a In normal operation, the end of arm 28 is kept out of engagement with the rotating knockoif wheel 30 by the thread 3! which passes through the tensioning device 32, past guide pin 33, and through the slotted portion 29 of arm 21 on its way to the reciprocating guide l2.

However, when the thread breaks, the L-shaped member 26 rotates about the pin 25 and causes 42 which is secured to the member by means of pin 43. The yoke 42 is adapted to fit around the threaded arm 45 which is pivotally mounted at 46 on the lug 41 of frame member I 5. The yoke is adjustably positioned around the arm 45 by means of nuts 48.

In the operation 'of this device'the pivoted member 40 is in the position shown by the full lines, when the package i8 is partially wound.

As the package grows in size, until it reaches the predetermined size indicated by the dotted lines at I8A, the frame member 15 recedes with the growth of the package to the position indicated by the dotted lines at 15A and in so doing moves back with it the threaded arm 45 which is pivotally secured thereto. As a consequence, pivoted member 40 is rotated about pin 25 until it assumes the position indicated by the dotted lines at 40B. As there shown, the free end of the member 40 engages the rotating knockofi wheel 30 and thus causes lever 20 to pivot about pin 2| and actuate the spindle-stopping mechanism.

To permit the production of packages of various predetermined sizes, the yoke 42 may be positioned at appropriate places along the threaded arm 45 by means of the nuts 48. To make a package of relatively small size, the yoke should be advanced toward the free end of the arm 45 whereas the converse would be the case if a.

larger size package were desired.

Although in the device as illustrated in the drawings the pivoted member 40 and the L- shaped member 26 are both mounted on the pin 25, it is not necessary that the arm be mounted at this particular position on lever 20. Similarly, the pivoted end of the threaded arm 45 need not be mounted on the lug 41 but may be otherwise suitably secured to the frame member l5. In addition, the yoke 42 could be replaced by any other suitable means permitting the positioning of the pivoted member 40 at various places along the threaded arm 45; for ex ample, the arm 45 could be slotted and ,the end of the arm 40 could be adapted to fit into the appropriate slots necessary to produce a yarn package of the desired size.
